Table REF  reports the Running Time Comparisons of our approach and the existing
state-of-the-art approaches. In this experiment, the running time is measured on a single RTX 2070 Super GPU, Intel i7-10700 CPU, and 32 GB RAM with batch size 1.
Since the multi-task structure of [1]} and our method, the run times of the bottom show great superiority over any top-down method. As shown in Tab. REF , our method achieves superior performance, significantly faster than the competing methods. Additionally, our method processing time is roughly constant regardless of the number of people and is more efficient in terms of model size (#Params) and computation complexity (GFLOPs) as shown in Fig REF .
